Pandemics and Biosecurity: CEPI puts a Bundibugyo vaccine in trialsBackground
Merck & Co., known as MSD outside the United States and Canada, is one of the world's largest pharmaceutical companies, with a portfolio spanning oncology, vaccines, animal health and hospital medicines sold worldwide.
Its vaccines franchise includes licensed shots against the Zaire strain of Ebola, and a separate $30m programme is improving MSD's manufacturing of that rVSV-ZEBOV vaccine. Manufacturing partnerships extend its reach into diseases too commercially marginal to develop alone.
One such partnership is Merck's stake in Hilleman Laboratories, its Singapore-based joint venture with the Wellcome Trust: on 31 July 2026 Hilleman advanced a vaccine candidate for the Bundibugyo strain of Ebola into clinical-trial production, drawing on Merck's manufacturing know-how rather than its own core research budget .
